Hello students, we are given by a question in which we have to find the stable form of the oxygen.
00:06
So the stable form of oxygen are oxygens 16, oxygen's 17 and oxygen 18.
00:23
Then the same same thing in the form of the oxygen is atomic.
00:33
Number, atomic number is same of these species that is 8 and the different is atomic mass now we have to find the particle that calls stability so the particles particles cause stability to an atom are neutrons and protons.
01:11
This is because of the reason that the n by p ratio should be equals to 1.
01:21
If the n by p ratio is 1, then the molecule will be stable or the atom will be stable.
01:27
But if n by p ratio is greater than 1, the molecule or the atom will be unstable because the atom becomes radioactive.
01:38
Now the particle that not affect the stability, so the particle that does not affect the stability of the atom is electrons.
01:49
Electrons because the electrons do not affect the n by p ratio.
01:55
Now we have to find that what are isotopes.
01:59
So the isotopes are those species, those species which have which have different atomic masses but same atomic number.
02:30
So these are known as iso -sop...
